Smoke alarms: Do they require to be connected on their own circuit or can they be taken off a JB with perm. feed?
I am also told they have to be interconnected?is this per Part P regs?
I have already got the power feeds in but no interlink to other smokes. I am now looking into RF smoke detectors if the interlink is required. Are RF detectors approved as part of a system?
Looking for guidance.
